HOUSTON, Feb. 2 -- Statoil ASA and partners plan to invest 1.2 billion kroner ($180 million) to improve oil and gas recovery from Vigdis field in the Norwegian North Sea.
Statoil expects to increase the recovery factor for the Vigdis East reservoir to 42% of original oil in place from 29% with water injection.
In the second phase of its Vigdis extension project, it plans to install a four-slot template through which one production well and one water injector will be drilled.
The new template will be tied back to existing seabed templates on Vigdis field. The template is to be installed during the second half of the year, and the first well is to be drilled during the first half of 2007.
Statoil let contracts to FMC Kongsberg for design and delivery of the subsea production systems, Saipem for use of the Saipem 7000 heavy lift vessel for installation of the template and manifold, and Stolt Offshore for manufacture and installation of flexible pipelines as well as installation and connection of umbilicals.
Vigdis produces through subsea templates tied back to Statoil's Snorre A tension leg platform 7 km away, with well-stream transfer in two pipelines (OGJ Online, Aug. 12, 2005).
Statoil, operator, holds 28.22% of the Vigdis license. Its partners are Petoro 30%, Norsk Hydro Production AS 13.28%; ExxonMobil Corp. 10.5%, Idemitsu Petroleum Norge AS 9.6%, Total E&P Norge AS 5.6%, and RWE DEA Norge AS 2.8%.
